// USING THESE TABLES

Read the table’s scope

A nominal catalog dimension is useful for identification. It is not the full tolerance, inspection or acceptance requirement. Use the series-specific guide for the scope of each table and ask Webson about your complete requirement.

Engineering approval, drawing requirements and the purchase order govern whether a proposed component is acceptable. Use our document cross-reference for standard status and ask Webson to quote the complete requirement.
